This is an artificial and biodegradable are two adjectives you don’t usually see united by the conjunction, and. However, it is worth noting that the artificial material is initially derived from a natural material, cellulose. Here’s more from a May 16, 2018 news item on ScienceDaily,

At DESY’s [Deutsches Elektronen-Synchrotron] X-ray light source PETRA III, a team led by Swedish researchers has produced the strongest bio-material that has ever been made. The artifical, but bio-degradable cellulose fibres are stronger than steel and even than dragline spider silk, which is usually considered the strongest bio-based material. The team headed by Daniel Söderberg from the KTH Royal Institute of Technology in Stockholm reports the work in the journal ACS Nano of the American Chemical Society.

The ultrastrong material is made of cellulose nanofibres (CNF), the essential building blocks of wood and other plant life. Using a novel production method, the researchers have successfully transferred the unique mechanical properties of these nanofibres to a macroscopic, lightweight material that could be used as an eco-friendly alternative for plastic in airplanes, cars, furniture and other products. “Our new material even has potential for biomedicine since cellulose is not rejected by your body”, explains Söderberg.

The scientists started with commercially available cellulose nanofibres that are just 2 to 5 nanometres in diameter and up to 700 nanometres long. A nanometre (nm) is a millionth of a millimetre. The nanofibres were suspended in water and fed into a small channel, just one millimetre wide and milled in steel. Through two pairs of perpendicular inflows additional deionized water and water with a low pH-value entered the channel from the sides, squeezing the stream of nanofibres together and accelerating it.

This process, called hydrodynamic focussing, helped to align the nanofibres in the right direction as well as their self-organisation into a well-packed macroscopic thread. No glue or any other component is needed, the nanofibres assemble into a tight thread held together by supramolecular forces between the nanofibres, for example electrostatic and Van der Waals forces.

With the bright X-rays from PETRA III the scientists could follow and optimise the process. “The X-rays allow us to analyse the detailed structure of the thread as it forms as well as the material structure and hierarchical order in the super strong fibres,” explains co-author Stephan Roth from DESY, head of the Micro- and Nanofocus X-ray Scattering Beamline P03 where the threads were spun. “We made threads up to 15 micrometres thick and several metres in length.”

Measurements showed a tensile stiffness of 86 gigapascals (GPa) for the material and a tensile strength of 1.57 GPa. “The bio-based nanocellulose fibres fabricated here are 8 times stiffer and have strengths higher than natural dragline spider silk fibres,” says Söderberg. “If you are looking for a bio-based material, there is nothing quite like it. And it is also stronger than steel and any other metal or alloy as well as glass fibres and most other synthetic materials.” The artificial cellulose fibres can be woven into a fabric to create materials for various applications. The researchers estimate that the production costs of the new material can compete with those of strong synthetic fabrics. “The new material can in principle be used to create bio-degradable components,” adds Roth.

The study describes a new method that mimics nature’s ability to accumulate cellulose nanofibres into almost perfect macroscale arrangements, like in wood. It opens the way for developing nanofibre material that can be used for larger structures while retaining the nanofibres’ tensile strength and ability to withstand mechanical load. “We can now transform the super performance from the nanoscale to the macroscale,” Söderberg underlines. “This discovery is made possible by understanding and controlling the key fundamental parameters essential for perfect nanostructuring, such as particle size, interactions, alignment, diffusion, network formation and assembly.” The process can also be used to control nanoscale assembly of carbon tubes and other nano-sized fibres.

(There are some terminology and spelling issues, which are described at the end of this post.)

Let’s get back to a material that rivals spider silk and steel for strength (for some reason that reminded me of an old carnival game where you’d test your strength by swinging a mallet down on a ‘teeter-totter-like’ board and sending a metal piece up a post to make a bell ring). From a May 16, 2018 DESY press release (also on EurekAlert), which originated the news item,

Terminology and spelling

I’ll start with spelling since that’s the easier of the two. In some parts of the world it’s spelled ‘fibres’ and in other parts of the world it’s spelled ‘fibers’. When I write the text in my post, it tends to reflect the spelling used in the news/press releases. In other words, I swing in whichever direction the wind is blowing.

For diehards only

As i understand the terminology situation, nanocellulose and cellulose nanomaterials are interchangeable generic terms. Further, cellulose nanofibres (CNF) seems to be another generic term and it encompasses both cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF). Yes, there appear to be two CNFs. Making matters more interesting is the fact that cellulose nanocrystals were originally christened nanocrystalline cellulose (NCC). For anyone who follows the science and technology scene, it becomes obvious that competing terminologies are the order of the day. Eventually the dust settles and naming conventions are resolved. More or less.

Ordinarily I would reference the Nanocellulose Wikipedia entry in my attempts to clarify the issues but it seems that the writers for the entry have not caught up to the current naming convention for cellulose nanocrystals, still referring to the material as nanocrystalline cellulose. This means, I can’t trust the rest of the entry, which has only one CNF (cellulose nanofibres).

I have paid more attention to the NCC/CNC situation and am not as familiar with the CNF situation. Using, NCC/CNC as an example of a terminology issue, I believe it was first developed in Canada and it was Canadian researchers who were pushing their NCC terminology while the international community pushed back with CNC.

CNC are not all made equal. The CNC produced by CelluForce is called CelluForce NCCTM and has specific properties and are especially easy to disperse. CelluForce NCCTM is the base material that CelluForce uses in all its products. This base material can be modified and tailored to suit the specific needs in various applications.

These, days CNC is almost universally used but NCC (not as a trademark) is a term still employed on occasion (and, oddly, the researchers are not necessarily Canadian).

Should anyone have better information about terminology issues, please feel free to comment.

Production and Applications Development of Cellulose Nanocrystals (CNC) at InnoTech Alberta

The production and use of cellulose nanocrystals (CNC) is an emerging technology that has gained considerable interest from a range of industries that are working towards increased use of “green” biobased materials. The construction of one-of-a-kind CNC pilot plant [emphasis mine] at InnoTech Alberta and production of CNC samples represents a critical step for introducing the cellulosic based biomaterials to industrial markets and provides a platform for the development of novel high value and high volume applications. Major key components including feedstock, acid hydrolysis formulation, purification, and drying processes were optimized significantly to reduce the operation cost. Fully characterized CNC samples were provided to a large number of academic and research laboratories including various industries domestically and internationally for applications development.

Canada scene update

InnoTech Alberta was until Nov. 1, 2016 known as Alberta Innovates – Technology Futures. Here’s more about InnoTech Alberta from the Alberta Innovates … home page,

Effective November 1, 2016, Alberta Innovates – Technology Futures is one of four corporations now consolidated into Alberta Innovates and a wholly owned subsidiary called InnoTech Alberta.

You will find all the existing programs, services and information offered by InnoTech Alberta on this website. To access the basic research funding and commercialization programs previously offered by Alberta Innovates – Technology Futures, explore here. For more information on Alberta Innovates, visit the new Alberta Innovates website.

As for InnoTech Alberta’s “one-of-a-kind CNC pilot plant,” I’d like to know more about it’s one-of-a-kind status since there are two other CNC production plants in Canada. (Is the status a consequence of regional chauvinism or a writer unfamiliar with the topic?). Getting back to the topic, the largest company (and I believe the first) with a CNC plant was CelluForce, which started as a joint venture between Domtar and FPInnovations and powered with some very heavy investment from the government of Canada. (See my July 16, 2010 posting about the construction of the plant in Quebec and my June 6, 2011 posting about the newly named CelluForce.) Interestingly, CelluForce will have a booth at nano tech 2017 (according to its Jan. 27, 2017 news release) although the company doesn’t seem to have any presentations on the schedule. The other Canadian company is Blue Goose Biorefineries in Saskatchewan. Here’s more about Blue Goose from the company website’s home page,

Blue Goose assists companies and research groups in the development of applications for CNC, by offering CNC for sale without Intellectual Property restrictions. [emphasis mine]

Bravo to Blue Goose! Unfortunately, I was not able to determine if the company will be at nano tech 2017.

One final comment, there was some excitement about CNC a while back where I had more than one person contact me asking for information about how to buy CNC. I wasn’t able to be helpful because there was, apparently, an attempt by producers to control sales and limit CNC access to a select few for competitive advantage. Coincidentally or not, CelluForce developed a stockpile which has persisted for some years as I noted in my Aug. 17, 2016 posting (scroll down about 70% of the way) where the company announced amongst other events that it expected deplete its stockpile by mid-2017.

The race to find applications for cellulosic nanomaterials continues apace. The latest entrant is from Clemson University in South Carolina (US). From a July 27, 2016 news item on Nanowerk,

Trees that are removed during forest restoration projects could find their way into car bumpers and fenders as part of a study led by Srikanth Pilla of Clemson University.

Pilla is collaborating on the study with researchers from the USDA Forest Service’s Forest Products Laboratory in Madison, Wisconsin.

The Madison researchers are converting some of those trees into liquid suspensions of tiny rod-like structures with diameters 20,000 times smaller than the width of a human hair. Pilla is using these tiny structures, known as cellulosic nanomaterials, to develop new composite materials that could be shaped into automotive parts with improved strength.

The auto parts would also be biorenewable, which means they could go to a composting facility instead of a landfill when their time on the road is done. The research could help automakers meet automotive recycling regulations that have been adopted in Europe and could be on the way to the United States.

Pilla, an assistant professor in the Department of Automotive Engineering at Clemson University, wants to use the composite materials he is creating to make bumpers and fenders that will be less likely to distort or break on impact.

“They will absorb the energy and just stay intact,” he said. “You won’t have to replace them because there will be no damage at all. Parts made with current materials might resist one impact. These will resist three or four impacts.”

A July 27, 2016 Clemson University media release, which originated the news item, describes the project and the reason for the support provides an interesting view of the politics behind the science (Note: A link has been removed),

Craig Clemons, a materials research engineer at the Forest Products Laboratory and co-principal investigator on the project, said that the Forest Service wants to find large-volume uses for cellulosic nanomaterials.

“We find appropriate outlets for all kinds of forest-derived materials,” he said. “In this case, it’s cellulosic nanomaterials. We’re trying to move up the value chain with the cellulosic nanomaterials, creating high-value products out of what could otherwise be low-value wood. We’ll be producing the cellulosic nanomaterials, which are the most fundamental structural elements that you can get out of wood and pulp fibers. We’ll also be lending our more than 25 years of experience in creating composites from plastics and wood-derived materials to the project.”

The research is environmentally friendly from start to finish.

The cellulosic nanomaterials could come from trees that are removed during forest restoration projects. Removing this material from the forests helps prevent large, catastrophic wildfires. Researchers will have no need to cut down healthy trees that could be used for other purposes, Pilla said.

Ted Wegner, assistant director at the Forest Products Laboratory, said, “The use of cellulosic nanomaterials will help meet the needs of people for sustainable, renewable and lightweight products while helping to improve the health and condition of America’s forests. The United States possesses abundant forest resources and the infrastructure to support a large cellulosic nanomaterials industry. Commercialization of cellulosic nanomaterials has the potential to create jobs, especially in rural America.”

One of the technical challenges Pilla and Clemons face in their work is combining the water-friendly cellulosic nanomaterials with the water-unfriendly polymers. They will need to show that the material can be mass produced because automakers need to make thousands of parts.

“We will use supercritical fluid as a plasticizer, allowing the nanoreinforcements to disperse through the polymer,” Pilla said. “We can help develop a conventional technique that will be scalable in the automotive sector.”

Robert Jones, executive vice president for academic affairs and provost at Clemson, congratulated Pilla on the research, which touches on Jones’ area of expertise.

Jones has a bachelor’s in forest management, a master’s in forestry from Clemson and a doctorate in forest ecology from the State University of New York College of Environmental Science and Forestry, Syracuse University.

“The research that Srikanth Pilla is doing with the USDA Forest Service is a creative way of using what might otherwise be a low-value wood product to strengthen automobile parts,” Jones said. “It’s even better that these parts are biorenewable. The research is good for the Earth in more ways than one.”

This research could grow in importance if the United States were to follow the European Union’s lead in setting requirements on how much of a vehicle must be recovered and recycled after it has seen its last mile on the road.

“In the U.S., such legislation is not yet here,” Pilla said. “But it could make its way here, too.”

Pilla is quickly establishing himself as a leading expert in making next-generation automotive parts. He won the 2016 Robert J. Hocken Outstanding Young Manufacturing Engineer Award from the nonprofit student and professional organization SME.

Pilla is nearing the end of the first year of a separate $5.81-million, five-year grant from the Department of Energy. As part of that research, Pilla and his team are developing ultra-lightweight doors expected to help automakers in their race to meet federal fuel economy standards.

Zoran Filipi, chair of Clemson’s automotive engineering, said that Pilla is playing a key role in making Clemson the premiere place for automotive research.

“Dr. Pilla is doing research that helps Clemson and the auto industry stay a step ahead,” Filipi said. “He is anticipating needs automakers will face in the future and seeking solutions that could be put into place very quickly. His research with the USDA Forest Service is another example of that.”

Congratulations also came from Anand Gramopadhye, dean of Clemson’s College of Engineering, Computing and Applied Sciences.

“Dr. Pilla’s work continues to have an impact on automotive engineering, especially in the area of manufacturing,” Gramopadhye said. “His innovations are positioning Clemson, the state, and the nation for strength into the future.”

This search for applications is a worldwide competition. Cellulose is one of the most abundant materials on earth and can be derived from carrots, bananas, pineapples, and more. It just so happens that much of the research in the northern hemisphere focuses on cellulose derived from trees in an attempt to prop up or reinvigorate the failing forest products industry.

In Canada we have three production facilities for cellulosic nanomaterials. There’s a plant in Alberta (I’ve never seen a name for it), CelluForce in Windsor, Québec, and Blue Goose Biorefineries in Saskatchewan. I believe Blue Goose derives their cellulosic from trees and other plant materials while the Alberta and CelluForce plants use trees only.

CelluForce Update

CelluForce represents a big investment by the Canadian federal government. The other companies and production facilities have received federal funds but my understanding is that CelluForce has enjoyed significantly more. As well, the company has had a stockpile of cellulose nanocrystals (CNC) that I first mentioned here in an Oct. 3, 2013 post (scroll down about 75% of the way). A June 8, 2016 CelluForce news release provides more information about CelluForce activities and its stockpile,

In the first half of 2016, Cellulose nanocrystals (CNC) shipments to industrial partners have reached their highest level since company inception.

Recent application developments in the oil & gas, the electronics and plastics sectors are expected to lead to commercial sales towards year end.

New website to enhance understanding of CelluForce NCCTM core properties and scope of performance in industrial applications is launched.

Montreal, Québec – June 8th 2016 – CelluForce, a clean technology company, is seeing growing interest in its innovative green chemistry product called cellulose nanocrystals (CNC) and has recorded, over the first half of 2016, the largest CNC shipment volumes since the company’s inception.

“Over the past year, we have been actively developing several industry-specific applications featuring CelluForce NCCTM, a form of cellulose nanocrystals which is produced in our Windsor plant. Three of these applications have now reached a high level of technical and commercial maturity and have been proven to provide cost benefits and sustained performance in the oil & gas, electronics and plastics segments,” said Sebastien Corbeil [emphasis mine], President and CEO of CelluForce. “Our product development teams are extremely pleased to see CelluForce NCCTM [nanocrystalline cellulose; this is a trade name for CNC] now being used in full scale trials for final customer acceptance tests”.

With the current shipment volumes forecast, the company expects to deplete its CelluForce NCCTM inventory by mid-2017 [emphasis mine]. The inventory depletion will pave the way for the company to start commercial production of CNC at its Windsor plant next year.

CelluForce has built a strong network of researchers with academic and industrial partners and continues to invest time and resources to develop, refine and expand applications for CNC in key priority industrial markets. Beyond oil & gas, electronics and plastics, some of these markets are adhesives, cement, paints and coatings, as well as personal and healthcare.

Furthermore, as it progressively prepares for commercial production, CelluForce has revamped its digital platform and presence, with the underlying objective of developing a better understanding of its product, applications and its innovative green technology capabilities. Its new brand image is meant to convey the innovative, versatile and sustainable properties of CNC.

Nice to see that there is sufficient demand that the stockpile can be eliminated soon. In my last piece about CelluForce (a March 30, 2015 post), I noted an interim president, René Goguen. An April 27, 2015 CelluForce news release announced Sebastien Corbeil’s then new appointment as company president.

One final note, nanocrystalline cellulose (NCC) was the generic name coined by Canadian scientists for a specific cellulose nanomaterial. Over time, cellulose nanocrystals (CNC) became the preferred term for the generic material and CelluForce decided to trademark NCC (nanocrystalline cellulose) as their commercial brand name for cellulose nanocrystals.

#BCTECH Summit 2016*, a joint event between the province of British Columbia (BC, Canada) and the BC Innovation Council (BCIC), a crown corporation formerly known as the Science Council of British Columbia, launched on Jan. 18, 2016. I have written a preview (Jan. 17, 2016 post) and a commentary on the new #BCTECH strategy (Jan. 19, 2016 posting) announced by British Columbia Premier, Christy Clark, on the opening day (Jan. 18, 2016) of the summit.

I was primarily interested in the trade show/research row/technology showcase aspect of the summit focusing (but not exclusively) on nanotechnology. Here’s what I found,

One of the major problems with creating nanoparticles is ensuring a consistent size and rapid production. According to Shell Ip, a Precision NanoSystems field application scientist, their NanoAssemblr Platform has solved the consistency problem and a single microfluidic cartridge can produce 15 ml in two minutes. Cartridges can run in parallel for maximum efficiency when producing nanoparticles in greater quantity.

The NanoAssemblr Platform is in use in laboratories around the world (I think the number is 70) and you can find out more on the company’s About our technology webpage,

The NanoAssemblr™ Platform

The microfluidic approach to particle formulation is at the heart of the NanoAssemblr Platform. This well-controlled process mediates bottom-up self-assembly of nanoparticles with reproducible sizes and low polydispersity. Users can control size by process and composition, and adjust parameters such as mixing ratios, flow rate and lipid composition in order to fine-tune nanoparticle size, encapsulation efficiency and much more. The system technology enables manufacturing scale-up through microfluidic reactor parallelization similar to the arraying of transistors on an integrated chip. Superior design ensures that the platform is fast and easy to use with a software controlled manufacturing process. This usability allows for the simplified transfer of manufacturing protocols between sites, which accelerates development, reduces waste and ultimately saves money. Precision NanoSystems’ flagship product is the NanoAssemblr™ Benchtop Instrument, designed for rapid prototyping of novel nanoparticles. Preparation time on the system is streamlined to approximately one minute, with the ability to complete 30 formulations per day in the hands of any user.

The company is located on property known as the Endowment Lands or, more familiarly, the University of British Columbia (UBC).

A few comments before moving on, being able to standardize the production of medicine-bearing nanoparticles is a tremendous step forward which is going to help scientists dealing with other issues. Despite all the talk in the media about delivering nanoparticles with medication directly to diseased cells, there are transport issues: (1) getting the medicine to the right location/organ and (2) getting the medicine into the cell. My Jan. 12, 2016 posting featured a project with Malaysian scientists and a team at Harvard University who are tackling the transport and other nanomedicine) issues as they relate to the lung. As well, I have a Nov. 26, 2015 posting which explores a controversy about nanoparticles getting past the ‘cell walls’ into the nucleus of the cell.

The next ‘nano’ booths were,

4D Labs located at Simon Fraser University (SFU) was initially hailed as a nanotechnology facility but these days they’re touting themselves as an ‘advanced materials’ facility. Same thing, different branding.

They advertise services including hands-on training for technology companies and academics. There is a nanoimaging facility and nanofabrication facility, amongst others.

I spoke with their operations manager, Nathaniel Sieb who mentioned a few of the local companies that use their facilities. (1) Nanotech Security (featured here most recently in a Dec. 29, 2015 post), an SFU spinoff company, does some of their anticounterfeiting research work at 4D Labs. (2) Switch Materials (a smart window company, electrochromic windows if memory serves) also uses the facilities. It is Neil Branda’s (4D Labs Executive Director) company and I have been waiting impatiently (my May 14, 2010 post was my first one about Switch) for either his or someone else’s electrochromic windows (they could eliminate or reduce the need for air conditioning during the hotter periods and reduce the need for heat in the colder periods) to come to market. Seib tells me, I’ll have to wait longer for Switch. (3) A graduate student was presenting his work at the booth, a handheld diagnostic device that can be attached to a smartphone to transmit data to the cloud. While the first application is for diabetics, there are many other possibilities. Unfortunately, glucose means you need to produce blood for the test when I suggested my preference for saliva the student explained some of the difficulties. Apparently, your saliva changes dynamically and frequently and something as simple as taking a sip of orange juice could result in a false reading. Our conversation (mine, Seib’s and the student’s) also drifted over into the difficulties of bringing products to market. Sadly, we were not able to solve that problem in our 10 minute conversation.

FPInnovations is a scientific research centre and network for the forestry sector. They had a display near their booth which was like walking into a peculiar forest (I was charmed). The contrast with the less imaginative approaches all around was striking.

FPInnovation helped to develop cellulose nanocrystals (CNC), then called nanocrystalline cellulose (NCC), and I was hoping to be updated about CNC and about the spinoff company Celluforce. The researcher I spoke to was from Sweden and his specialty was business development. He didn’t know much about CNC in Canada and when I commented on how active Sweden has been its pursuit of a CNC application, he noted Finland has been the most active. The researcher noted that making the new materials being derived from the forest, such as CNC, affordable and easily produced for use in applications that have yet to be developed are all necessities and challenges. He mentioned that cultural changes also need to take place. Canadians are accustomed to slicing away and discarding most of the tree instead of using as much of it as possible. We also need to move beyond the construction and pulp & paper sectors (my Feb. 15, 2012 posting featured nanocellulose research in Sweden where sludge was the base material).

Other interests at the Summit

I visited:

“The Wearable Lower Limb Anthropomorphic Exoskeleton (WLLAE) – a lightweight, battery-operated and ergonomic robotic system to help those with mobility issues improve their lives. The exoskeleton features joints and links that correspond to those of a human body and sync with motion. SFU has designed, manufactured and tested a proof-of-concept prototype and the current version can mimic all the motions of hip joints.” The researchers (Siamak Arzanpour and Edward Park) pointed out that the ability to mimic all the motions of the hip is a big difference between their system and others which only allow the leg to move forward or back. They rushed the last couple of months to get this system ready for the Summit. In fact, they received their patent for the system the night before (Jan. 17, 2016) the Summit opened.

It’s the least imposing of the exoskeletons I’ve seen (there’s a description of one of the first successful exoskeletons in a May 20, 2014 posting; if you scroll down to the end you’ll see an update about the device’s unveiling at the 2014 World Cup [soccer/football] in Brazil).

Unfortunately, there aren’t any pictures of WLLAE yet and the proof-of-concept version may differ significantly from the final version. This system could be used to help people regain movement (paralysis/frail seniors) and I believe there’s a possibility it could be used to enhance human performance (soldiers/athletes). The researchers still have some significant hoops to jump before getting to the human clinical trial stage. They need to refine their apparatus, ensure that it can be safely operated, and further develop the interface between human and machine. I believe WLLAE is considered a neuroprosthetic device. While it’s not a fake leg or arm, it enables movement (prosthetic) and it operates on brain waves (neuro). It’s a very exciting area of research, consequently, there’s a lot of international competition.

Delightfully, after losing contact for a while, I reestablished it with the folks (Sean Lee, Head External Relations and Jim Hanlon, Chief Administrative Officer) at TRIUMF (Canada’s national laboratory for particle and nuclear physics). It’s a consortium of 19 Canadian research institutions (12 full members and seven associate members).

It’s a little disappointing that TRIUMF wasn’t featured in the opening for the Summit since the institution houses theoretical, experimental, and applied science work. It’s a major BC (and Canada) science and technology success story. My latest post (July 16, 2015) about their work featured researchers from California (US) using the TRIUMF cyclotron for imaging nanoscale materials and, on the more practical side, there’s a Mar. 6, 2015 posting about their breakthrough for producing nuclear material-free medical isotopes. Plus, Maclean’s Magazine ran a Jan. 3, 2016 article by Kate Lunau profiling an ‘art/science’ project that took place at TRIUMF (Note: Links have been removed),

“It’s not every day that most people get to peek inside a world-class particle physics lab, where scientists probe deep mysteries of the universe. In September [2015], Vancouver’s TRIUMF—home to the world’s biggest cyclotron, a type of particle accelerator—opened its doors to professional and amateur photographers, part of an event called Global Physics Photowalk 2015. (Eight labs around the world participated, including CERN [European particle physics laboratory], in Geneva, where the Higgs boson particle was famously discovered.)”

Here’s the local (Vancouver) jury’s pick for the winning image (from the Nov. 4, 2015 posting [Winning Photographs Revealed] by Alexis Fong on the TRIUMF website),

With all those hexagons and a spherical shape, the DESCANT looks like a ‘buckyball’ or buckminsterfullerene or C60 to me.

I hope the next Summit features TRIUMF and/or some other endeavours which exemplify, Science, Technology, and Creativity in British Columbia and Canada.

Onto the last booth,

MITACS was originally one of the Canadian federal government’s Network Centres for Excellence projects. It was focused on mathematics, networking, and innovation but once the money ran out the organization took a turn. These days, it’s describing itself as (from their About page) “a national, not-for-profit organization that has designed and delivered research and training programs in Canada for 15 years. Working with 60 universities, thousands of companies, and both federal and provincial governments, we build partnerships that support industrial and social innovation in Canada.”Their Jan. 19, 2016 news release (coincidental with the #BCTECH Summit, Jan. 18 – 19, 2016?) features a new report about improving international investment in Canada,

“Opportunities to improve Canada’s attractiveness for R&D investment were identified:

1.Canada needs to better incentivize R&D by rebalancing direct and indirect support measures

3.Canada needs to invest in training programs that grow the knowledge economy”

Oddly, entrepreneurial/corporate/business types never have a problem with government spending when the money is coming to them; it’s only a problem when it’s social services.

Back to MITACS, one of their more interesting (to me) projects was announced at the 2015 Canadian Science Policy Conference. MITACS has inaugurated a Canadian Science Policy Fellowships programme which in its first year (pilot) will see up up to 10 academics applying their expertise to policy-making while embedded in various federal government agencies. I don’t believe anything similar has occurred here in Canada although, if memory serves, the Brits have a similar programme.

Finally, I offer kudos to Sherry Zhao, MITACS Business Development Specialist, the only person to ask me how her organization might benefit my business. Admittedly I didn’t talk to a lot of people but it’s striking to me that at an ‘innovation and business’ tech summit, only one person approached me about doing business. Of course, I’m not a male aged between 25 and 55. So, extra kudos to Sherry Zhao and MITACS.

Christy Clark (Premier of British Columbia), in her opening comments, stated 2800 (they were expecting about 1000) had signed up for the #BCTECH Summit. I haven’t been able to verify that number or get other additional information, e.g., business deals, research breakthroughs, etc. announced at the Summit. Regardless, it was exciting to attend and find out about the latest and greatest on the BC scene.

I wish all the participants great and good luck and look forward to next year’s where perhaps we’ll here about how the province plans to help with the ‘manufacturing middle’ issue. For new products you need to have facilities capable of reproducing your devices at a speed that satisfies your customers; see my Feb. 10, 2014 post featuring a report on this and other similar issues from the US General Accountability Office.

At the mention of cellulose nanocrystals (CNC), my interest was piqued. From a Nov. 10, 2015 news item on Nanotechnology Now,

Ceapro Inc. (TSX VENTURE:CZO) (“Ceapro” or the “Company”), a growth-stage biotechnology company focused on the development and commercialization of active ingredients for healthcare and cosmetic industries, announced that Bernhard Seifried, Ph.D., Ceapro’s Senior Research Scientist and a co-inventor of its proprietary Pressurized Gas Expanded Technology (PGX) will present this morning [Nov. 10, 2015] at the prestigious 2015 Composites at Lake Louise engineering conference.

A Nov. 10, 2015 Ceapro press release, which originated the news item, describes the technology in a little more detail and briefly mentions cellulose nanocrystals (Note: A link has been removed),

Dr. Seifried will make a podium presentation entitled, “PGX – Technology: A versatile technology for generating advanced biopolymer materials,” which will feature the unique advantages of Ceapro’s enabling technology for processing aqueous solutions or dispersions of high molecular weight biopolymers, such as starch, polysaccharides, gums, pectins or cellulose nanocrystals, into open-porous morphologies, consisting of nano-scale particles and pores.

Gilles Gagnon, M.Sc., MBA, President and CEO of Ceapro, stated, “Our disruptive PGX enabling technology facilitates biopolymer processing at a new level for generating unique highly porous biopolymer morphologies that can be impregnated with bioactives/APIs or functionalized with other biopolymers to generate exfoliated nano-composites and novel advanced material. We believe this technology will provide transformational solutions not only for our internal programs, but importantly, can be applied much more broadly for Companies with whom we intend to partner globally.”

Utilizing its PGX technology, Ceapro successfully produces its bioactive pharmaceutical grade powder formulation of beta glucan, which is an ingredient in a number of personal care cosmeceutical products as well as a therapeutic agent used for wound healing and a lubricative agent integrated into injectable systems used to treat conditions like urinary incontinence. The Company is developing its enabling PGX platform at the commercial scale level. In order to fully exploit the use of this innovative technology, Ceapro has recently decided to further expand its new world-class manufacturing facility by 10,000 square feet.

“The PGX platform generates unique morphologies that are not possible to produce with other conventional drying systems,” Mr. Gagnon continued. “The ultra-light, highly porous polymer structures produced with PGX have a huge potential for use in an abundant number of applications ranging from functional foods, nutraceuticals, drug delivery and cosmeceuticals, to advanced technical applications.”

Ceapro’s novel PGX Technology can be utilized for a wide variety of bio-industrial processing applications including:

Impregnate the polymer matrix homogeneously with thermo-sensitive bioactives and/or hydrophobic modifiers to tune solubility of the final polymer bioactive matrix all in the same processing equipment at mild conditions (40⁰C).

The highly tune-able PGX process can generate exfoliated nano-composites and highly porous morphologies ranging from sub-micron particles (50nm) to micron-sized granules (2mm), as well as micro- and nanofibrils, granules, fine powders and aerogels with porosities of >99% and specific surface areas exceeding 300 m2/gram. The technology is based on a spray drying method, operating at mild temperatures (40°C) and moderate pressures (100-200 bar) utilizing PGX liquids, which is comprised of a mixture of food grade, recyclable solvents, generally regarded as safe (GRAS), such as pressurized carbon dioxide and anhydrous ethanol. The unique properties of PGX liquids afford single phase conditions and very low or vanishing interfacial tension during the spraying process. This then allows the generation of extremely fine particle morphologies with high porosity and a large specific surface area resulting in favorable solubilisation properties. This platform drying technology has been successfully scaled up from lab scale to pilot scale with a processing capacity of about 200 kg/hr of aqueous solutions.

“Alberta Innovates-Technology Futures is proud to host and operate Western Canada’s only CNC pilot plant,” said Stephen Lougheed, AITF’s President and CEO. “Today’s commissioning is an important milestone in our ongoing efforts to provide technological know-how to our research and industry partners in their continued applied R&D and commercialization efforts. We’re able to provide researchers with more CNC than ever before, thereby accelerating the development of commercial applications.”

Members of Alberta’s and Western Canada’s growing CNC communities of expertise and interest spent the afternoon exploring potential commercial applications for the cellulose-based ‘wonder material.’

I have not been able to find any online trace of the plant’s grand opening. But I did find a few things. The AITF website has a page dedicated to CNC and its pilot plant and there’s a slide show about CNC and occupational health and safety from members of Alberta’s CNC Pilot Plant Research Team for their project, which started in 2014.

No mention in the Alberta media materials is ever made of CelluForce, a CNC production plant in the province of Québec, which predates the Alberta plant by more than 18 months (my Dec. 15, 2011 posting).

One last comment, CNC or cellulose nanocrystals are sometimes called nanocrystalline cellulose or NCC. This is a result of Canadians who were leaders at the time naming the substance NCC but over time researchers and producers from other countries have favoured the term CNC. Today (2015), the NCC term has been trademarked by Celluforce.

The most one can gather from the news item/press release is that CelluForce is researching applications in the oil and gas sector and that they’re very happy to receive money although there’s no indication as to how much. From a March 26, 2015 news item on Azonano,

CelluForce is pleased to announce an investment into the company by Schlumberger, the world’s leading supplier of technology, integrated project management and information solutions for the global oil and gas industry.

This investment furthers the collaboration between CelluForce and Schlumberger to explore the use of CelluForce’s wood-derived nano-crystalline cellulose (CelluForce NCCTM) to enhance the productivity of oil and gas wells.

“We are very proud to be expanding our partnership with Schlumberger, the world’s leading oil and gas service company”, stated René Goguen, Acting President of CelluForce. “We have always believed that NCC applications hold promise extending far beyond the forest sector, and we see this investment from an international company as respected as Schlumberger as confirmation of this belief.”

NCC is a fundamental building block of trees that can be extracted from the forest biomass and has unique properties that offer a wide range of potential applications. Measured in units as small as nanometres, these tiny structures have strength properties comparable to steel and will have uses in a variety of industrial sectors.

The first small-scale NCC pilot plant was built and began operation in 2006 at FPInnovations’ laboratory in Montréal, Québec. Supported in part by Natural Resources Canada and the Ministère de l’Énergie et des Ressources naturelles du Québec, the pilot plant operation led to a scalable NCC production process and placed Canada in the pole position of the global race towards commercial NCC manufacture. Based on the success of the small-scale pilot plant, CelluForce, a joint venture of Domtar and FPInnovations, was created which led to the construction of a demonstration plant at Domtar’s mill in Windsor, Québec, having a production capacity of 1000 kg of NCC per day.

This announcement follows the recent announcement by the Honourable Greg Rickford, Minister of Natural Resources, of a $4.0 million contribution by Sustainable Development Technology Canada (SDTC) to optimize the extraction process of NCC from dry wood pulp and develop applications for its use in the oil and gas sector.

The $4M Canadian federal government investment was mentioned in my Feb. 19, 2015 post (scroll down about 40% of the way).

I get the feeling CelluForce is trying to recover from a setback and I wonder if it has anything to do with their production facility’s stockpile of NCC (aka, CNC or cellulose nanocrystals), first mentioned here in an Oct. 3, 2013 post. There was much fanfare about producing NCC/CNC but there was and is no substantive demand for the material in Canada or anywhere else globally.

Canada has three facilities that produce CNC (CelluForce being the largest) and there are production facilities in other countries. To date, there is no major application for CNC but given its properties, there is substantive research into how it could be commercialized. My Nov. 25, 2014 post covers a recent US report about commercializing nanocellulosic materials, including CNC.

I hope that CelluForce is able to overcome whatever problems it seems to be experiencing. Certainly, investments such as Schlumberger’s hint at the possibility. I wish the management team good luck.

SAPPI (formerly South African Pulp and Paper Industries) has announced it will build a nanocellulose facility in the Netherlands. From a March 11, 2015 news item on Nanowerk,

Sappi Limited, a leading global producer of dissolving wood pulp and graphics, speciality and packaging papers, is pleased to announce that it will build a pilot-scale plant for low-cost Cellulose NanoFibrils (nanocellulose) production at the Brightlands Chemelot Campus in Sittard-Geleen in the Netherlands. The pilot plant is expected to be operational within nine months.

Commenting on the decision, Andrea Rossi, Group Head Technology, Sappi Limited, explained that the pilot plant will help with Sappi’s move into new adjacent business fields based on renewable raw materials. Sappi’s strategy includes seeking growth opportunities by producing innovative performance materials from renewable resources. The raw material for the pilot plant would be supplied from any of Sappi’s Saiccor, Ngodwana and Cloquet dissolving wood pulp plants. The pilot plant is the precursor for Sappi to consider the construction of a commercial CNF plant.

He goes on to say “the pilot plant will test the manufacturing of dry re-dispersible Cellulose NanoFibrils (CNF) using the proprietary technology developed by Sappi and Edinburgh Napier University. The location of the pilot plant at Brightlands Chemelot Campus provides Sappi with easy access to multiple partners with whom Sappi will seek to co-develop products that will incorporate CNF across a large variety of product applications to optimise performance and to create unique characteristics for these products.

The CNF produced by Sappi will have unique morphology, specifically modified for either hydrophobic or hydrophilic applications. Products produced using Sappi’s CNF will be optimally suitable for conversion in lighter and stronger fibre-reinforced composites and plastics, in food and pharmaceutical applications, and in rheology modifiers as well as in barrier and other paper and coating applications.

Speaking on behalf of Brightlands Chemelot Campus, the CEO Bert Kip said “We’re proud that a globally leading company like Sappi has chosen our campus for their new facility. The initiative perfectly fits with our focus area on bio-based materials and our new pilot plant infrastructure.”

In December 2014, Sappi and Edinburgh Napier University announced the results of their 3 year project to find a low cost energy-saving process that would allow Sappi to produce the nanocellulose on a commercially viable basis – and importantly without producing large volumes of chemical waste water associated with existing techniques. At the time, Professor Rob English, who led the research with his Edinburgh Napier colleague, Dr. Rhodri Williams, said “What is significant about our process is the use of unique chemistry, which has allowed us to very easily break down the wood pulp fibers into nanocellulose. There is no expensive chemistry required and, most significantly, the chemicals used can be easily recycled and reused without generating large quantities of waste water.

Math Jennekens, R&D Director at Sappi Europe who is the project coordinator and will oversee the pilot plant, said “We are very excited to be able to move from a bench top environment into real-world production. Our targeted run-rate will be 8 tons per annum. We will produce a dry powder that can be easily redispersed in water. The nanocellulose is unmodified which makes it easier to combine with other materials. The product will be used to build partnerships to test the application of our nanocellulose across the widest range of uses.”

He went on to thank the Government of the Province of Limburg in the Netherlands for their significant support and financial contribution towards the establishment of the pilot plant.

This business with a pilot production plant reminds me of CelluForce which has a cellulose nanocrystal (CNC) or, as it’s also known, nanocellulose crystal (NCC) production plant located in Windsor, Québec. They too announced a production plant which opened to fanfare in January 2012. in my Oct. 3, 2013 post (scroll down about 60% of the way) I noted that production had stopped in August 2013 due to a growing stockpile. As of March 11, 2015, I was not able to find any updates about the stockpile on the CelluForce website. The most recent CelluForce information I’ve been able to find is in a Feb. 19, 2015 posting (scroll down about 40% of the way).

The February 2015 issue of Industrial Biotechnology is hosting a special in depth research section on the topic of cellulose nanotechnology. A Feb. 19, 2015 news item on Phys.org features a specific article in the special section (Note: A link has been removed),

Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity—whether ingested, inhaled, on contact with the skin, or on exposure to cells within the body—is a topic of intense discussion, and the latest evidence and insights on cellulose nanocrystal toxicity are presented in a Review article in Industrial Biotechnology.

Maren Roman, PhD, Virginia Tech, Blacksburg, VA, describes the preparation of cellulose nanocrystals (CNCs) and highlights the key factors that are an essential part of studies to assess the potential adverse health effects of CNCs by various types of exposure. In the article “Toxicity of Cellulose Nanocrystals: A Review” , Dr. Roman discusses the current literature on the pulmonary, oral, dermal, and cytotoxicity of CNCs, provides an in-depth view on their effects on human health, and suggests areas for future research.

There has been much Canadian investment both federal and provincial in cellulose nanocrystals (CNC). There’s also been a fair degree of confusion regarding the name. In Canada, which was a research leader initially, it was called nanocrystalline cellulose (NCC) but over time a new term was coined cellulose nanocrystals (CNC). The new name was more in keeping with the naming conventions for other nanoscale cellulose materials such as cellulose nanofibrils, etc. Hopefully, this confusion will resolve itself now that Celluforce, a Canadian company, has trademarked NCC. (More about Celluforce later in this post.)

Getting back to toxicity and CNC, here’s a link to and a citation for Maron’s research paper,

The article is open access at this time. For anyone who doesn’t have the time to read it, here’s the conclusion,

Current studies of the oral and dermal toxicity of CNCs have shown a lack of adverse health effects. The available studies, however, are still very limited in number (two oral toxicity studies and three dermal toxicity studies) and in the variety of tested CNC materials (CelluForce’s NCC). Additional oral and dermal toxicity studies are needed to support the general conclusion that CNCs are nontoxic upon ingestion or contact with the skin. Studies of pulmonary and cytotoxicity, on the other hand, have yielded discordant results. The questions of whether CNCs have adverse health effects on inhalation and whether they elicit inflammatory or oxidative stress responses at the cellular level therefore warrant further investigation. The toxicity of CNCs will depend strongly on their physicochemical properties—in particular, surface chemistry, including particle charge, and degree of aggregation, which determines particle shape and dimensions. Therefore, these properties—which in turn depend strongly on the cellulose source, CNC preparation procedure, and post-processing or sample preparation methods, such as lyophilization, aerosolization, sonication, or sterilization—need to be carefully measured in the final samples.

Another factor that might affect the outcomes of toxicity studies are sample contaminants, such as endotoxins or toxic chemical impurities. Samples for exposure tests should therefore be carefully analyzed for such contaminants prior to testing. Ideally, because detection of toxic chemical contaminants may be difficult, control experiments should be carried out with suitable blanks from which the CNCs have been removed, for example by membrane filtration. Moreover, especially in cytotoxicity assessments, the effect of CNCs on pH and their aggregation in the cell culture medium need to be monitored. Only by careful particle characterization and exclusion of interfering factors will we be able to develop a detailed understanding of the potential adverse health effects of CNCs.

If I understand this rightly, CNC seems safe (more or less) when ingested orally (food/drink) or applied to the skin (dermal application) but inhalation seems problematic and there are indications that this could lead to inflammation of lung cells. Other conclusions suggest both the source for the cellulose and CNC preparation may affect its toxicity. I encourage you to read the whole research paper as this author provides good explanations of the terms and summaries of previous research, as well as, some very well considered research.

The article is part of an IB IN DEPTH special research section entitled “Cellulose Nanotechnology: Fundamentals and Applications,” led by Guest Editors Jose Moran-Mirabal, PhD and Emily Cranston, PhD, McMaster University, Hamilton, Canada. In addition to the Review article by Dr. Roman, the issue includes Reviews by M. Rose, M. Babi, and J. Moran-Mirabal (“The Study of Cellulose Structure and Depolymerization Through Single-Molecule Methods”) and by X.F. Zhao and W.T. Winter (“Cellulose/cellulose-based nanospheres: Perspectives and prospective”); Original Research articles by A. Rivkin, T. Abitbol, Y. Nevo, et al. (“Bionanocomposite films from resilin-CBD bound to cellulose nanocrystals), and P. Criado, C. Fraschini, S. Salmieri, et al. (“Evaluation of antioxidant cellulose nanocrystals and applications in gellan gum films”); and the Overview article “Cellulose Nanotechnology on the Rise,” by Drs. Moran-Mirabal and Cranston.

CelluForce welcomes the announcement by Sustainable Development Technology Canada (SDTC) of a contribution of $4.0 million to optimize the extraction process of Nanocrystaline Cellulose (NCC) from dry wood pulp and develop applications for its use in the oil and gas sector. The announcement was made in Quebec City today [Feb. 16, 2015] by the Honourable Greg Rickford, Minister of Natural Resources and Minister for the Federal Economic Development Initiative for Northern Ontario.

NCC is a fundamental building block of trees that can be extracted from the forest biomass and has unique properties that offer a wide range of potential applications. Measured in units as small as nanometres, these tiny structures have strength properties comparable to steel and will have uses in a variety of industrial sectors. In particular, NCC is touted as having the potential to significantly advance the oil and gas industry.

“Our Government is positioning Canada as a global leader in the clean technology sector by supporting innovative projects aimed at growing our economy while contributing to a cleaner environment,” said the Honourable Greg Rickford, Canada’s Minister of Natural Resources. [emphasis mine] “By developing our resources responsibly, exploring next-generation transportation and advancing clean energy technology, the projects announced today will create jobs and improve innovation opportunities in Quebec and across Canada.”

“World-class research led to the development of this ground breaking extraction process and placed Canada at the leading edge of NCC research”, stated René Goguen, Acting President of CelluForce Inc. “This announcement by SDTC sets the stage for the pre-commercial development of applications that will not only support Canada’s forest sector but also the oil and gas sector, both of which are important drivers of the Canadian economy.”

This project will further improve and optimize the process developed by CelluForce to extract nanocrystalline cellulose (CelluForce NCC™) from dry wood pulp. In addition to improving the extraction process, this project will investigate additional applications for the oil-and-gas industry such as cementing using this renewable forestry resource.

There’s very little information in this news release other than the fact that CelluForce’s $4M doesn’t need to be repaid seeing it’s described as a ‘contribution’ rather than an investment. The difference between a contribution and a grant, which is what these funds used to be called, somewhat mystifies me unless this is a translation issue.

As for the news release content, it is remarkably scant. This $4M will be spent on improving the extraction process and on applications for the oil and gas industry. Neither the improvements nor the possible applications are described. Hopefully, the government has some means of establishing whether or not those funds (sorry, the contribution) were used for the purposes described.

I am glad to see this in this news release, “Our Government is positioning Canada as a global leader in the clean technology sector …” although I’m not sure how it fits with recent attempts to brand environmentalists as part of an ‘anti-petroleum’ movement as described in a Feb. 19, 2015 post by Glyn Moody for Techdirt (Note: A link has been removed),

As Techdirt has been warning for some time, one of the dangers with the flood of “anti-terrorist” laws and powers is that they are easily redirected against other groups for very different purposes. A story in the Globe and Mail provides another chilling reminder of how that works:

The RCMP [Royal Canadian Mounted Police] has labelled the “anti-petroleum” movement as a growing and violent threat to Canada’s security, raising fears among environmentalists that they face increased surveillance, and possibly worse, under the Harper government’s new terrorism legislation.

As the Globe and Mail article makes clear, environmentalists are now being considered as part of an “anti-petroleum” movement. That’s not just some irrelevant rebranding: it means that new legislation supposedly targeting “terrorism” can be applied.

…

It seems logically incoherent to me that the government wants clean tech while condemning environmentalists. Whether or not you buy climate change science (for the record, I do), you have to admit that we are running out of petroleum. At heart, both the government and the environmentalists have to agree that we need new sources for fuel. It doesn’t make any sense to spend valuable money, time, and resources on pursuing environmentalists.

This business about the ‘anti-petroleum’ movement reminds me of a copyright kerfuffle including James Moore, currently the Minister of Industry, and writer Cory Doctorow. Moore, Minister of Canadian Heritage at the time, at some sort of public event, labeled Doctorow as a ‘radical extremist’ regarding his (Doctorow’s) views on copyright. The comments achieved notoriety when it appeared that Moore and the organizers denied the comments ever took place. The organizers seemed to have edited the offending video and Moore made public denials. You can read more about the incident in my June 25, 2010 post. Here’s an excerpt from the post which may explain why I feel there is a similarity,

… By simultaneously linking individuals who use violence to achieve their ends (the usual application for the term ‘radical extremists’) to individuals who are debating, discussing, and writing commentaries critical of your political aims you render the term into a joke and you minimize the violence associated with it.

Although with ‘anti-petroleum’, it seems they could decide any dissension is a form of violence. It should be noted that in Canada the Ministry of Industry, is tightly coupled with the Ministry of Natural Resources since the Canadian economy has been and continues to be largely resource-based.

For anyone interested in CelluForce and NCC/CNC, here’s a sampling of my previous posts on the topic,

Over 230 delegates from 25 countries gathered in Vancouver, British Columbia, Canada last week at TAPPI’s 9th International Conference on Nanotechnology for Renewable Nanomaterials. “This year’s conference was exceptional,” noted co-chair Wadood Hamad, Priniciple Scientist, FPInnovations. “The keynote and technical presentations were of very high quality. The advancements made in many applications show great promise, and we will see expanded commercial use of these renewable biomaterials.”

Several key commercial announcements were made at this year’s conference, highlighting the tangible growth in this emerging market area of renewable biopolymers:

Celluforce, which opened their commercial plant in January 2012, shared six advanced commercial projects.

Imerys announced the launch of their new FiberLean™ MFC innovative composite, which enables a 10-15% reduction in fiber usage for papermaking applications.

Representatives from the newly formed BioFilaments shared information on their unique high performance biomaterial derived from wood cellulose to be used as reinforcing agents and rheological modifiers.

Nippon Paper Industries introduced Cellenpia, their cellulose nanofibers produced from their pre-commercial plant.

GL&V presented their commercial system, developed with the University of Maine, to produce cellulose nanofibrils at a very low energy cost.

American Process Inc. presented their latest results of producing lignin-coated nanocellulose particles using their AVAP® technology which produces a material that is more easily dispersed and has enhanced properties.

Another day, another award for Dr. Richard Berry, as per this May 22, 2014 news item on Nanowerk (Note: A link has been removed),

Dr. Richard Berry of CelluForce has been named the first recipient of TAPPI’s International Nanotechnology Division’s Technical Award. This award recognizes outstanding accomplishments or contributions which have advanced the responsible and sustainable production and use of renewable nanomaterials. Dr. Berry will be presented with this award at TAPPI’s 2014 International Conference on Nanotechnology for Renewable Materials to be held June 23-26, 2014 in Vancouver, British Columbia.

Currently Vice-President and Chief Technology Officer for CelluForce, Berry has had a storied career (from the news item),

Prior to moving to CelluForce in 2011 he was Principal Scientist and leader of the nanotechnology initiative at FPInnovations. … He’s received many awards including the Nano-industry award from Nano Québec for his exceptional contribution to the development of cellulose nanocrystals, the Purvis Memorial Award and he’s been named one of Canada’s Clean 50 honourees. The initiatives Dr. Berry has spearheaded in recent years have allowed Canada to position itself as a world leader in the development of the new nanotechnology industry. This work was recognised through the 2012 NSERC Synergy award for innovation given to McGill University, FPInnovations, ArboraNano, and CelluForce .. .

I notice that the news item uses the term cellulose nanocrystals (CNC) rather than nanocrystalline cellulose (NCC). Perhaps this means someone will put me out of my misery soon and declare one term or other the winner.

As for the reference to Canada as a “a world leader in the development of the new nanotechnology industry,” that seems a little grandiose and odd. To my knowledge, no one refers to a ‘nanotechnology industry’. I believe the writer is trying say that Canada is a leader in the production of CNC. I wonder if they’ve (CelluForce) dealt with their stockpile first mentioned here in an Oct. 3, 2013 posting and again in an April 10, 2014 posting about the US Dept. of Agriculture’s workshop on commercializing cellulose nanomaterials. Should anyone know of the stockpile’s status at this time, please do let me know.
